The A-Lert Retrofit Process: The Industry Standard

A-Lert custom fabricates each roofing project in order to ensure quality. Continuous roof panels, roll formed at the jobsite, eliminate lap joints and the associated leak potential. The roof panels are attached to the framing system with floating clips which accommodate the normal expansion and contraction of the metal panels. The clips are concealed when the interlocking roof panels have been mechanically seamed together. Sealant applied to the panel ribs provides a further barrier against water penetration.
